Steinel 110030691 Heat Shrink Solder Butt Connector, 0.5-1.5 mm², White, 10 pcs

Creating reliable, waterproof electrical connections in automotive, marine, or industrial wiring often requires soldering and separate sealing steps. The Steinel 110030691 Crimpverbinder solves this with an integrated heat shrink solder butt connector: a low-temperature solder ring and adhesive-lined polyolefin sleeve combine into one step. Insert the stripped wires, apply heat, and the solder melts while the sleeve shrinks to form a corrosion-resistant, IP67-rated seal.

Who is it for

Electricians, automotive technicians, and marine installers who need durable, weatherproof splices for stranded or solid conductors from 0.5 to 1.5 mm² (AWG 22–16). The transparent sleeve allows visual inspection of the solder joint before final installation.

Main features

• Integrated low-temperature solder ring for a strong, gas-tight connection
• Adhesive-lined polyolefin sleeve provides IP67 waterproofing and strain relief
• Transparent insulation lets you confirm proper solder flow
• Shrink ratio 2:1, minimum shrink temperature 80°C, solder melt temperature 138°C
• Rated for 600 V with 1 kV dielectric strength
• Operating temperature range from -55°C to +125°C
• Pack of 10 white connectors

Tips

Use a heat gun with a deflector nozzle for even heating. Start at the center of the connector and move outward to ensure the solder melts before the sleeve fully shrinks. Avoid open flames, which can overheat the polyolefin and damage the seal.
